I have found my balance improving recently and reflecting on my falls prevention work with older people who report similar experiences when practicing Tai Chi – so when a student mentioned her problems with Vertigo I thought I would do a quick bit of research. It seems that this is quite well documented so here are some links which I found interesting:
